SQLite Reader

Reading data from an SQLite data base

In order to read data from an SQLite database, use the following source definition:

<Source config="[configuration]">sqlite://[SQL query]</Source>

Any SQL query which is supported by SQLite can be passed into the SQL Query parameter. All resulting fields will be interpreted as strings.

For the configuration, there are two possibilities:

• Using a connection string directly
• Using a connection string which is located in a text file

Using a connection string directly

Pass the connection string directly into the configuration of the source tag:

<Source config="Data Source=c:\\Temp\\mydb.db; Version=3">sqlite://select * from MyTable where wage &gt; 1000</Source>

Please note the use of double backslashes inside the string and the substitution of the greater (>, >) operator in the SQL query (needed for XML compliance).

Parameters can be used inside the connection string, if needed.

Using a connection string inside a text file

In order to read the connection string from a file, use the following syntax (using the @ character):

<Source config="@sqlite_connection.txt">sqlite://select * from MyTable where wage &gt; 1000</Source>

Sample content of the sqlite_connection.txt file, also using a parameter (§env§):

Data Source=c:\Temp\§env§\mydb.db; Version=3
